Which plan to pickFree is enough for typo-catching. If you write for clients or customers every day, Pro on yearly billing is good value; paying monthly costs more than double.Start on Free. Pro is cheap and covers about 250 pages a month, enough for most individuals. Take Team once more than one person translates, because users are free and you only pay for the shared quota.Try Free on a chapter or a long blog post. If it clicks, Premium on yearly billing is good value, and the lifetime deal pays off after about three years. Premium Pro is for authors who want daily critiques and the workshops.
